Abstract
Apparatus for separately adjusting the shut height of individual tools on a progressive forging machine 'on the fly' when the machine is running. The apparatus includes individual load bearing wedge blocks on the slide for supporting associated tool cassettes. Each wedge block is displaced by a secondary wedge-like cam driven by an associated power actuator. The wedge geometry yields a compact, rugged construction. The cassettes are supported by precision located surfaces that allow desired axial adjustment without loss of alignment with opposed dies.
